I have never seen or heard of a "no God" protest.
We do have an Establishment Clause in the Constitution which prevents us from favoring any official religion or flavor of one... This is because of how the fighting about nations being Catholic or Protestant tore apart European nations.

No. DJT loves autocrats because bullying is natural for him, since is doesn't require reading, attention to details, or an ability to concentrate.

Education, travel, and other experiences where you actually meet people different from the set with which you grew up/are familiar--all of these help you see others as people just like yourself, the way Jesus wants us to see others (cf. the Parable of the Good Samaritan).
DJT and other bullies want you to hate whom they hate as a way of controlling YOU. If you are busy hating, you don't have empathy and you can't see the hated at people like yourself.
You should question why someone repeatedly asks you to listen to your
worse angels, rather than calling you to listen to your
better angels.
